Okay. These guys are the best when it comes to the late-night rush (4 cars in the drive-thru at 12:30 AM). The late-night crew is super friendly, even with my ridiculous "custom" order: Animal Style Cheeseburger, extra tomatoes, no pickles; Animal Fries, well done; and a chocolate-strawberry shake. No complaints, ever!
But inside, it's hectic and jumbled all the time (except for post 11 PM). 3 PM post-lunch slow down? Not here. Expect at least a 25 minute wait for food on the weekends.
If you've never eaten at In-N-Out, you're missing out.
